Net cage for aquaculture and culturing method

Abstract

The invention provides a novel net cage for aquaculture and a culturing method. A plurality of independent net cages with same shapes but different mesh sizes are stacked and used for aquaculture. Themesh sizes of the net cages in each layer are different, the mesh size of the net cage in the inner layer is larger, smaller-sized aquatic organisms can be leaked and larger-sized aquatic organisms can be retained, so that the problems that the aquatic organisms obtained during collection have different sizes and need manual sorting are solved. The collection process automatically achieves manual sorting functions, and the operation is simple, efficient and labor-saving.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a net cage and a culture method for aquaculture. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. The enhancement of aquatic resources may also be included. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage fish farming and fence farming. Aquatic organism...
